抜粋

In order to enhance the trapped field in cryo-cooled HTSC bulks using pulse field magnetizing (PFM), a metal ring (stainless steel 304 and/or Al) has been tightly set onto the SmBaCuO bulk disk and the relation between the total trapped flux Φ TP, the trapped field B T P, and the temperature rise ΔT, has been investigated as a function of the applied pulse field B ex. The Φ T P and B T P values are enhanced about 10-20% by the metal ring due to the reduction in the temperature rise AT. These results suggest that a part of the generated heat Q due to the flux motion in the peripheral region promptly transfers to the metal ring and the heat transfer to the cold stage is improved by the ring setting.
